CU LTIVATO R.

SPECIFICATION forming part of Letters Patent No. 558,456, dated April 14:, 1896.

Application filed January 24, 1895. Renewed March 9, 1896. Serial No. 582,493. (No model.)

To all whom it may concern.-

Be it known that I, JOSIAH H. Moons, of Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates to the construction of cultivator-blades, to the means employed for connecting them with and adjusting them on the cultivator, and to the draft-hitch of a certain class of cultivators. Itis exemplified in the structure hereinafter described, and it is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is a side elevation of a cultivator embodying the different features of my improvement. Fig. 2 is a perspective representation of one of the cultivator-blades. Fig. 3 is a similar representation of a crossbar having a set of blades attached thereto. Fig. 4 is an end view of a blade and connection, indicating the manner of adjusting the blade. Fig. 5 is a side outline of the drafthitch bracket, showing the manner in which it extends sidewisefrom the beam.

The arch of the cultivator is shown at 1, the tongue thereof at 2, and a beam at 3, such beam being pivoted on the arch between its ends. Caster-rods 4 pivot vertically in the forward ends of the beams and extend rearward therefrom. IVheels 5 are journaled on the caster-rods and normally maintain positions under the beams and substantially in line with the arch. The hitch-bracket 6 is secured to the beam, one on each side of the cultivator, and it extends outward and downward, as shown in Fig. 5. A set of hitchholes, or their equivalent, are formed in the bracket at diiferent elevations, and link 7 connects the bracket with the lower end of swinging bar 8, which connects at its upper end with a cross-bar ofthe cultivator and is supplied with a singletree between its ends in the usual manner. As the hitch-bracket extends downward from the pivot of the beam at right angles with the general direction of the beam, the draft of the team may be utilized to any desired extent in forcing the blades into the ground, such tendency being increased by lowering the hitch of the link on the bracket, and vice versa, and the lower end of the bracket is sufficiently far from the wheel to permit free play thereof.

An arch-bar or other connection is used to join each beam to a cross-bar 10, such archbar being shown at 9 in Fig. 1, in connection with other elements that are preferably used, but which have no direct relation to the present invention. The cross-bar has a number of concave bearings 11 in its under side, such bearings conforming to segments ofcylinders laid crosswise of the bar. The cultivatorblades 13 are runner-shapedthat is to say, they are turned upward at their forward ends, and the forward extremity of each is hooked sidewise in curves that approximately conform to the concavities of the bearings.

The hooked ends of the blades are placed in the bearings of the bar, as shown in Figs. 3 and 4, and staple-bolts 12, which engage the hooked ends of the blades and pass through holes in the bar, are used to secure the blades to the bar. It is well to make the curve of the bearings to correspond with the curve of a circle having a slightly shorter diameter than a circle corresponding with the curve of the hooks, as indicated in Fig. 4, in which case the staple-bolts will tend to spring the hooks into the concavities and make a somewhat securer connection.

The blades are sharpened at a and b, are turned upward at c, and are hooked, as specified, at (1. Their front edges cut through the soil, their upward extensions have no tendency to drag trash, and they may be set to any desired angle, as indicated in Fig. 4, by loosening the bolts, shifting the blades, and retightening the bolts.

The cultivator is to be supplied with a cross-bar for each beam, and each crossbar may be supplied with as many blades as is desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A runner-shaped cultivator-blade having its front end turned upward and curved flatwise over the longitudinal axis of the blade, in a manner to form an arc of a circle, substantially as set forth.

2. In cultivators,the combination of a crossbar having concave bearings in its under side, runner-shaped blades having .their forward ends hooked sidewise to conform to the bearings of the cross-bar, and clamps for holding the hooked ends of the blades in the conoavities of the bar, substantially as set forth.

3. "In cultivators, the combination of an arch, beams pivoted to the arch at or near their longitudinal centers, caster wheels swung from the forward ends of the beams,

cultivating devices secured to the rear ends of the beams, and draft-hitch brackets extended outward and downward from the beams, substantially as set forth.

In testimony whereof I sign my name in the I 5 presence of two subscribing witnesses.
